Here’s another reason why “an apple a day keeps the doctor away” — according to new research findings published in theJournal of Leukocyte Biology, oral ingestion of apple polyphenols (antioxidants found in apple peels) can suppress T cell activation to prevent colitis in mice. This study is the first to show a role for T cells in polyphenol-mediated protection against an autoimmune disease and could lead to new therapies and treatments for people with disorders related to bowel inflammation, such as ulcerative colitis, Crohn’s disease and colitis-associated colorectal cancer.
